Hauv cov ntaub ntawv tshawb fawb thiab kev siv tshuab txuas ntxiv, viscoelasticity yog cov khoom ntawm cov ntaub ntawv uas nthuav tawm ob qho tib si viscous thiab elastic yam ntxwv thaum tab tom deformation… xeev ib zaug kev ntxhov siab raug tshem tawm.
YViscoelasticity ntawm polymer yog dab tsi?
Cov khoom uas nthuav tawm ob qho tib si viscous thiab elastic yam ntxwv thaum deformed nyob rau hauv kev ntxhov siabpaub tias yog viscoelastic. Thiab qhov no yuav suav nrog cov khoom siv polymeric-los ntawm butter mus rau lub kaus mom caij tsheb kauj vab. (Yog lawm, butter, lipid, muaj cov hlua ntev ntawm tib yam, rov ua cov molecules hu ua monomers, piv txwv li, ib qho polymer.
Tus cwj pwm viscoelastic txhais li cas?
Viscoelastic cwj pwm yog kev sib xyaw ntawm elastic thiab viscous tus cwj pwmqhov twg cov kev ntxhov siab thov ua rau muaj kev ywj pheej tam sim ntawd tom qab los ntawm qhov khov, lub sij hawm-dependent strain.
Qhov txawv ntawm elasticity thiab viscoelasticity yog dab tsi?
Qhov txawv ntawm cov ntaub ntawv elastic thiab cov ntaub ntawv viscoelastic yog cov ntaub ntawv viscoelastic muaj cov viscosity yam thiab cov elastic tsis txhob… ib qho load yog thov, ces tshem tawm; Txawm li cas los xij, cov tshuaj viscoelastic ua.
Cov ntaub so ntswg viscoelastic yog dab tsi?
Cov ntaub so ntswg lom tau ua qauv ua cov ntaub ntawv viscoelastic vim qhov tshwm sim ntawm hysteresis hauv lawv cov kev ntxhov siab so tus cwj pwm [21, 22]. Lo lus viscoelastic yog kev sib xyaw ntawm cov kua dej khov thiab elasticity, thiab yog li, cov khoom siv roj ntsha hauv qab kev ntxhov siab thiab cov kab mob tshwm sim ob qho tib si viscous thiab elasticity.
